Another very important object of. the in- Vention lies in the provision of an attachment of this nature whichmay be manufactured at a low cost and yet will prove thoroughlyeflicient and reliable in use'and well adapted for the purpose for which it is designed.

With the above and numerous other objects in view, as will appear as the descrip tion proceeds, the invention resides in certain details of construction as will be hereinafter more fully described and claimed.

In the drawing:

Figure 1 is an elevation of a felt conditioner suction box with my improved attachment thereon,

Fig. 2 is a top plan view thereof,

Fig. 3 is a perspective view of the attachment showing the same inverted,

Fi 4 is a detail sectional view taken substantlally on the line 4-4 of Fig. 2.

Referring to the drawings in detail it will be seen that 5 denotes generally a well known type of felt conditioner suction box now in quite common use. The upper surface of this conditioner is subjectto considerable wear as is well known and heretofore it has been the custom to discard the conditioner after the wear has become excessive. In order to eliminate this waste. I have devised an attachment in the form of an oblong plate 6 substantially rectangular in formation and provided with a longitudinally extending slot 7 at one end and a pair of openings 8 adjacent the other end, said openings and said slots being disposed along the median longitudinal dimension of the plate. 1

On the under surface of the plate along the side edges thereof I provide ribs 9 the inner surfaces of which are dove-tailed. On said under surface of the plate I also provide a transverse rib 10 along that end adjacent the slot 7. This plate takes the place of the worn surface on the conditioner. It will begapparent that the plate may be readily slid longitudinally over-the surface and V the dove-tailed ribs 9 will engage flanges 11 formed on the worn upper wall of the conditioner, asis clearly shown in Fig. 4. At one end the plate 6 is provided with a pendent flange 8*, the said flange 8* constituting a convenient handle or finger piece for the positioning or the removal of the plate 6. i i

The attachment is essentially a renewal part and has for its purpose to prevent the throwing away of the felt conditioner suction boxwhen the top surface thereof is worn, this attachment simply slips over the worn-outsurface and thus enables the felt conditioner to be used again, instead of being thrown away as is now the custom.

A swill be understood by comparison of Figures 1, 3 and 4, the worn-out box 5 can be machined with a taper slightly wider at one end than the other, and dove-tailed to receive my novel plate 6 which is machined slightly wider at one end than at. the other and is also dove-tailed so as to slip on the box 5 and be air tight without the employ ment of screws or other fastenings or extraneous means of any kind. It will also be understood that when machined as stated, the plate 6 is susceptible of being switched on and off without the assistance of any tools whatsoever.

The oblong slot 7 in the plate 6 is for suction purposes to hold the felt belt on the fluid ejecting element 12, the steam ejecting element. 13, and the brush 14:, the said slot 7 being arranged in coincidence with said element as illustrated in Figure 2. The aper turesS are suction ports for the removal of any dirt that is brushed off the felt belt by the brush 14.

It is thought that the construction operation and advantages of this invention will now be clearly understood by those skilled in this art without a more detailed description thereof. The present embodiment of the invention has been disclosed in detail merely by way of example since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention andin the above description. Itwill be apparent, however, that changes in the details of construction, design, and the like may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.

Having thus described my invention hat I claim as new is:

1. In means for the purpose described, the combination with a box' opened at its upper side and machined so as to have a taper and to be Wider at one end than at the other,'a nd being dove tailed, of an apertured plate machined with a taper so as to be Wider at one end than the other and dove-tailed and adapted to he slipped endwise on the box and be tightly held to the box in air tight manner of itself.

2. In means for. the purpose described, the combination with a box opened at its upper side and machined so as to have a taper and to be Wider at one end than at the other, and being dove tailed, of an apertured plate inachined With a taper so as to be Wider at one end than the other and dove-tailed and adapted to be slipped endwise on the box and be tightly held to the box in air tight manner of itself; the said plate being equipped at one end with a pendent portion constituting a hand hold or finger piece.

3. In means for the purpose described, the

the combination with a box open at its upper side and flanged and dove tailed, fluidejecting means in the box, steam ejecting means also in the box and a brush in the box, of a plate having a pendent dove-tailed flange whereby it may be slid into engagement with and be held of itself on the box and having a slot in coincidence with said fluid and steam ejecting means and said brush and also having a suction port.

In testimony whereof I atfix my signature.
